Abstract
The present invention relates to a tunneling method by filling thin coal layer with coal gangue. Said method is characterized by that after the tunnel meeting production requirements is excavated in the thin coal layer zone, the width of said tunnel section is 1.5-2 m, at two sides of said tunnel a coal layer whose length is less than 12 m is respectively excavated along the thin coal layer, thenthe obtained coal body space can be filled up with coal gangue obtained by tunneling, if necessary, the filled coal gangue can be grouted.
Description
Technical field
The present invention relates to a kind of waste filling thin coal seam tunnelling method, be particularly useful for harder roof and floors such as limestone, sandstone.
Background technology
In thickness was thin seam mining below the 1.3m, crawlway digging gangue recovery ratio was big, and the rate of producing coal is low, and its cost is higher, at present for the digging of crawlway, did not also have the method for specially suitable its excavation cost of reduction.
Summary of the invention
The purpose of this invention is to provide a kind of waste filling thin coal seam tunnelling method, it is big to solve crawlway digging gangue recovery ratio, and the problem that the rate of producing coal is low reduces the tunnelling cost, and is implemented in down-hole digestion process digging gangue.
Waste filling thin coal seam tunnelling method of the present invention, excavate the wide 2～3m of being in the girdle zone, height is after 1.5～2m satisfies the drift section of regular production requirement, respectively excavate the coal seam of length in the both sides, tunnel along girdle again less than 12m, filling is carried out with the spoil that the tunnel excavates in coal body space after the extraction, carry out in case of necessity the spoil of filling is carried out slip casting, make it contact tight with base plate with seam roof, under the good situation of wall rock condition, the roadway support mode can be bare supporting, but during driving, top board is in a single day broken, should in time increase and hold up the canopy supporting.
Waste filling thin coal seam tunnelling method of the present invention, the coal body that makes full use of the extraction of both sides, tunnel are carried out the bastard coal displacement as the filling space.For the harder top board of country rock good adaptive capacity is arranged, be particularly useful for top boards such as limestone, sandstone, can effectively control under the condition of deformation of the surrounding rock in tunnel, realize that driving has more coal and goes out spoil less, reduces the tunnelling cost.This method is used for reference the operating principle of traditional stope drift active workings roadside packing gob side entry driving method, the other release in lane and colliery cancellation hillock-downhole gangue treatment technology, has concentrated from the source and has reduced the spoil output, has realized that spoil does not go out the advantage of well.Be better than the other waste filling gob side entry driving in traditional lane aspect safeguarding again in tunnelling, and improved the driving coal output of crawlway.This method easy construction after spoil and coal displacement, can be saved the tunnelling cost greatly.In addition, greatly reduce ten thousand tons of drivage ratios and go out the cash rate, reduced spoil and stacked the environment pollution that is brought with a ton coal.
Description of drawings
Accompanying drawing is a waste filling thin coal seam tunnelling section structure schematic diagram of the present invention.
Among the figure: 1-girdle top board, 2-waste filling layer, 3-girdle, 4-girdle base plate, 5-tunnel.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
Shown in the accompanying drawing, after excavating tunnel 5 sections that satisfy the regular production requirement, 5 both sides respectively excavate the coal seam of certain-length along girdle 3 in the tunnel again, the specification in tunnel 5 is generally: width is about 2.5m, girdle base plate 4 can reach about 1.8m apart from the height of girdle top board 1, about two help the coal body length maximum of the girdle 3 of extraction to reach about 10m.Adhere to beating shallow eye, few powder charge, improve roadway quality.The spoil that coal body space after the extraction excavates with the tunnel carries out filling to be reinforced, the time in case of necessity the spoil layer 2 of filling is carried out slip casting, it is tight that its and top, coal seam top board 1 contacts with seat earth 4, guarantees that the tunnel satisfies normally use.Under the good situation of wall rock condition, the roadway support mode can be bare supporting, but when driving, and top board will in time be modified to and hold up the canopy supporting in case broken.
Claims (1)
1. waste filling thin coal seam tunnelling method, excavate the wide 2～3m of being in the girdle zone, height is after 1.5～2m satisfies the drift section of regular production requirement, it is characterized in that: respectively excavate the coal seam of length along girdle less than 12m in the both sides, tunnel, filling is carried out with the spoil that the tunnel excavates in coal body space after the extraction, spoil to filling carries out slip casting in case of necessity, make it contact tight with base plate with seam roof, under the good situation of wall rock condition, the roadway support mode is bare supporting, during nude supporting driving, top board is in case broken, and timely increasing held up the canopy supporting.
